A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 19845-69-3, Name is 1,6-Bis(diphenylphosphino)hexane, molecular formula is C30H32P2. In a Article，once mentioned of 19845-69-3, Safety of 1,6-Bis(diphenylphosphino)hexane
Reactions of [Re2(CO)10] with Me3NO and diphosphines [Ph2P(CH2)nPPh2, n=1-6] yield mixtures of the monodentate-coordinated diphosphine complexes [Re 2(CO)9(eta1-P-P)] (P-P=Ph 2P(CH2)nPPh2, n=1-6) (yields 5-40%) and bridged dimers [{Re2(CO)9}2(mu-P-P)] (5-50%). These complexes were isolated as either equatorial or axial isomers, or a mixture of two isomers. Reactions of the monodentate complexes with Me 3NO yield close-bridged complexes [Re2(CO) 8(mu-P-P)] and phosphine oxide complexes [Re2(CO) 9{P-P(O)}]. The structures of the close-bridged complexes 1 (n=3) and 2 (n=4), were determined by X-ray crystallography. The Re-Re bond in the close-bridged complex with the longest phosphine chain (n=6) is readily cleaved in CDCl3 to give the complex [{cis-ReCl(CO)4} 2(mu-dpph)] (3) as the product, the structure of which was also determined by X-ray crystallography.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Safety of 1,6-Bis(diphenylphosphino)hexane. In my other articles, you can also check out more blogs about 19845-69-3
